Hai!
it might help to add your complaint via ab...@sendgrid.com.
I very much doubt it. Sendgrid's business is sending mail and they do not
care if that mail is spam or not. If enough servers block them they will go
away.
They do, however, apparently care about phishing - they did disable the
sendgrid redirect that some phisher has been spamming at me for the last
three weeks.
They definately do. I report to them and they do take them down pretty
quickly.
Inside SURBL we do list the abused CT links. Unfortunately SA doesnt make
use of the wildcarded list that SURBL delivers for a long time now.
So if you want to use it add:
util_rb_3tld ct.sendgrid.net
Inside your loca.cf
And while you are at it also add:
util_rb_2tld page.link
Bye, Raymond
